Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to an iron chip protection device for numerically controlled lathes. Background Art

[0002] A CNC lathe is a high-precision, high-efficiency automated machine tool equipped with a dedicated CNC system and a programmable controller. It can automatically process the parts to be processed according to a pre-programmed processing program. It is usually composed of a control system, a servo system, a detection system, a mechanical transmission system and other auxiliary systems. The main processing object of a CNC lathe is a rotating part. It is particularly suitable for processing complex workpieces such as shafts and sleeves. Its main working parts include a spindle box, an exchange gear box, a feed box, a slide box, a tool holder, a tailstock, a guide rod, a lead screw and a bed.

[0003] The utility model patent with authorization announcement number CN 219562363 U discloses an iron chip protection device for a CNC lathe. The device clamps the workpiece on a three-jaw chuck, then starts the driving guide rail to drive the tool holder to slide to one side. Under the action of the active slider and the push plate, the protective cover wraps the three-jaw chuck. The iron chips during processing will splash and impact the inner wall of the protective cover, and finally slide to the bottom of the protective cover. After the processing is completed, the inner protective cover is rotated to discharge the iron chips through its notch to the lower material hole, and are uniformly collected by a collection box. The above-mentioned prior art scheme still has the following deficiencies: Under normal circumstances, the iron chips generated during the processing of the workpiece are splashed everywhere. However, a notch is provided on the protective cover, and it cannot be guaranteed that all the iron chips generated during the processing of the workpiece fall into the inside of the protective cover instead of flying out from the notch. The protection and collection effect of the iron chips is general. Therefore, a kind of iron chip protection device for a CNC lathe is proposed to solve the above-mentioned problems.

The left side and the bottom of the electromagnet protection frame 25 are both open designs, and the front and back sides of the inner wall of the electromagnet protection frame 25 are both inclined designs. The two ends of the electromagnet protection frame 25 extend to the outside of the CNC lathe body 1, and the two ends are respectively connected to the positive and negative poles of the external power supply.

[0027] Through the above technical scheme, the workpiece to be processed is first fixed on the three-jaw chuck, and the tool is installed on the tool holder. During processing, the tool holder drives the tool to move. At the same time, under the transmission of the connecting rod 24, the electromagnet protection frame 25 moves together, and the two ends of the electromagnet protection frame 25 are respectively connected to the positive and negative poles of the power supply, so that the coil inside the electromagnet protection frame 25 is energized, and the current generates a magnetic field in the coil.

After the processing is completed, the electromagnet protection frame 25 is returned to its original position and the power is turned off. The iron filings inside it slide into the collection box 21 along the inclined inner wall of the electromagnet protection frame 25, thereby achieving the purpose of good iron filing collection effect.
